There is consequently an increasing requirement to consider emissions of NH3 when undertaking assessments which impact road traffic numbers close to sensitive ecological receptors or designated ecological sites. As NH3 is not a pollutant that currently falls under the Local Air Quality Management (LAQM), there are currently no D...
